RECEPTACLE CLOSURE Filed March 1'7, 1951 2 Sheets-Sheet 2 f6 INVENTOR.

I BY .4 4 p ATTORNEY.

Patented Aug. 1 1933 v UNITED STATES 7 My present invention has reference toreceptacles and closures therefor, and my primary object is the provision of means for automatically locking the closure on the receptacle when the said closure is pressed against the receptacle.

A further object is the provision of means for easily and quickly fastening a closure on thereceptacle in a-manner that 'will produce a tight joint between these members and. permit of the receptacle being subjected to roughusage without liability of the closure becoming detached therefrom. r i

A still further object is the provision of a device for this purpose in which the fastening means between a closure and receptacle also afiord'a hinged joint between these. members.

"A further object is to providea cover or closure for a butter tub or like receptacle with a resilient rim to snap into a grove formed in the body of the receptacle adjacent'its upper edge. A further object is the provision of means whereby the covers may be brought .to frictional engagement with each other to permit of the same being nested in stacks.

To the attainment of the foregoing and other objects which will presentthemselves the improvement also resides in certain other novel features ofconstruction, combination and operative association of' parts, satisfactory embodiments of which are disclosed by the accompanying drawmgs. v

Figure 9 is a sectionalview approximately on theline 9-9 of Figure 7. a In the drawings I have illustrated the invention in connection with a butter tub and its cover, although it is intended for use with other types of receptacles and its general application is contemplated by the claims. V In the drawings the numeral 10 indicates a tub or wooden receptacle having its outer corner and its mouth beveled and provided below the bevel with an annular groove :11. The mouth of the receptacle is surrounded by a metallicbetnd 12 shaped to conformwith the beveled comer 13 of the receptacle and likewise corrugated, as at 12',

to provide an internal groove which is received 7 in the groove 11 of the receptacle. g V The cover or closure of the receptacle isin the nature of alwooden' disc and isindicated by the numeral 13'. .The closure hasa rabbet i'n the upper portion of outer edge to provide. the

same with anannular'depress'ion 14. Arranged around the periphery of the cover thereis a metal; strip that affords a rim 16. The rim "is formed with an inwardly offset upper. portion 1'7 to occupy the shoulder provided with. the

'rabbet or recess in the; cover. The "rim is eX- tended a suitable distance below the inner face of the cover and is corrugated to provide the same with an annular inwardly rolled bead 19 that is designed to snap into the groove of the receptacle, as illustrated; by Figures 2; 3 and 4 of the drawings. To permit of the exact coengagement of the bead 19 with the groove 11 the rim 16 is-slit and hasits upper portion at one", g

end of the slit projected to "provide a tongue 18 which is riveted or otherwise connected to a portion of the rimand lappedfby thesaid tongue. 7

. The band" 12 is slitted longitudinally and transversely at one point andlthe metalbound by this slitis bent outwardly and downwardly to formthe same with a finger 20 designed'to 'be received in an'opening 21in the depending por tion of the rim and thereby affording. a hinged connection between the cover and the tongue. At a diametrically opposite point the band has its lower portion bulged outwardly from the top andtjhe angle wall ,22 provided by this bulged portion is formed with an opening. The resilient band, ata point diametrically opposite the part thereof provided with the opening 21' is PAT NT: OFFICE-.1."

formed with laterally extending portion or ffinger 23that is also provided with an opening; and there is designed to passthrou'gh theseopenings a metal strap 2; that carries a seal' 25. and thus prevent the cover from being surreptitiously removed from the tub.

The rim has a portion 12 so that a prying tool maybe readily engaged behind therim for removing the cover' from the tub.

of its rolled, bead I flattened and. pressed outwardly as at 26 for 'affordingaspacebetween the rim'and the band 'Only a slight' downward pressure needbefex erted: upon the co ver to bring i the same into locking engagement with the. closure andit W111 be noted that the coveris notpmy' effectively 7 locked on the tub but is hingedly connected therewith. I v v In Figures. 5 and 6 the "construction-1s sub- [stantiallypsimilar to that just described, .the

cover 28 being provided with the annular groove for the reception of the shouldered portion of the annular resilient rim 29. The rim has its depending portion or skirt formed-with spaced corrugations providing inwardly rolled beads 30-30; The beads do not extend the-entire circumference of the rim but terminate away from each other. In a like manner the metal rim 31 that is arranged around the mouth of "the tub is provided with spaced corrugations to afford inwardly directed grooves 32 ofthe samelength as the beads 30. The non-corrugated portions 34 of the rimpermit of the insertion of a sharp toolto spread the rim and to permit or the cover beingreadilyremoved from the tub.' In Figures 'l, 8'andi9 the tub 35 has'its' mouth surrounded ,by a metal ring .or band 36pmtides with a curcumferential inwardly directedj' corrugationsin which snap'the inwardly rolled" beads 37 of the splitmetaljand'resilient rim 38. In this instance the rim 33 is also in "the nature of a split member and thebeads do not extend around the entire circumference "thereof. The split ends of the'rizn'are arranged "in lapping relation and are connected together adjacent to their outer ends by means 39. The overlapping end of the rim is provided with an outturned flange 41) and inward thereof is provided with a round opening 41. There is pivotally secured to theunderlying end of the rim 7 the reduced and rounded end 42 of a stud 43 whose outer face is kerfed, as at 44. The enlarged and rounded body of the stud is freely passedthrough the opening 4:1 and the fiange .or lip '40 as well as the stud is provided with "openings for the reception of a wire 45 to which is attached a seal 46. When the stud is turned to the position disclosedby Figure '7 of the draw-- 'ings it will be noted that the same is in contacting engagement with the outer wall pro- 'vided by the opening-41, that is he walln'earest the flange or lip i0 and this obviously forces the ends of the split rim toward each, other so as to 'bringthe beads thereof into tight frictional engagement with the grooves in the mouth of the "tub: By the employment. of a screw .driver or like instrument inserted in the kerf of the stud the latter is turned in an opposite direction to bring the body portion thereof "away from the said wall provided by the said 'fopenin'g and further to contact with theoppois applied.

site or inner wall provided by the opening to spread the beaded portion-of the bandand to permit of the cover being readily removed from I .jthe tub- 'In'this instance the ends of the band exert a tension toward each other. and the body or skirt of the band normally springs inwardly but; of course, is ,yi'eld'able outwardly. As disclOsedby .Tigure e'the ring or band 36 may have a lower outward corrugation 47, and the rim 38 may have a -lower outward corrugation 481101111;"Q'Velthecolflllgatioli'i when the cover offsjetportion 1'7 afforded in the upper edge portion of the cover permits a plurality of the .covers to be nested one over the other, the

reducedor inwardly offset upper portion of. the

rim 'o'n 'one of the covers being receivedyby' the corrugated lower or skirt portion of thecover superposed thereon. ,Thus thecove'rs maybe I stacked and effectively posted and held en"- gagement without liability of accidental disassociation.

While it is believed that from the foregoing the nature and advantages of the invention will be readily apparent I desire to have it understood that ,I do not limit myself :to what is herein illustrated and described and that such changes may be resorted to when desired as fall within thescope of the appended claims.
